Problems solved by technology

However, the data collected by this method is limited, and usually only the information related to the soles of the feet can be analyzed, such as the longer part touching the ground, etc. The posture of the trunk part of the body cannot be monitored, which greatly affects the accuracy of the monitoring and evaluation of running posture. influences
In order to solve the above problems, a scheme of collecting joint detection data during motion and comparing it with standard data to obtain motion evaluation results is currently proposed. However, the above method may affect the evaluation results due to changes in the environment, making the accuracy less Can't meet demand

Abstract

The embodiment of the invention discloses a running posture evaluation method, device and equipment and a storage medium, and the method comprises the steps: obtaining a running video of a user, and the running video comprising at least one image frame; determining a running scene according to the running video; extracting a key image frame in the running video based on the running scene; and evaluating the running posture of the user according to the joint point data in the key image frame. According to the technical scheme, different key image frames in the running video caused by differentrunning scenes are considered, the running posture of the user can be evaluated according to the joint point data in the key image frames in different running scenes, and the accuracy of running evaluation is improved by distinguishing the running scenes in the running video of the user, so that the user is effectively helped to correct wrong running postures.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of motion capture and analysis, and in particular to a running posture evaluation method, device, equipment and storage medium. Background technique [0002] With the development of science and technology and the improvement of people's quality of life, people pay more and more attention to sports. In order to improve the effect of sports, more and more sports evaluation methods have been proposed. With the rise of sports software, running has become an increasingly popular sport among many sports. [0003] In the prior art, in order to guide people's running posture in a targeted manner, running information is generally collected through insoles or running shoes with sensor chips, and then the problems existing in the user's running are obtained through analysis. However, the data collected by this method is limited, and usually only the information related to the soles of the feet ca...
